Neco 2017 Physics Question 23
Practice objective / multiple choice question 23 from the 2017 Neco Physics examination.
A sealed gas container of volume 5.0\,L contains an ideal gas at 300\,K and pressure 1.00\times10^{5}\,Pa. The container is connected to a U‑tube manometer filled with mercury (density 13\,600\,kg·m^{-3}). The mercury column shows a height difference of 0.075\,m, indicating the gas pressure is higher than atmospheric. The atmospheric pressure is 1.01\times10^{5}\,Pa and remains unchanged. The gas is heated to 350\,K while the volume stays constant. Find the new height difference shown by the manometer (in metres, to three decimal places).
